My issue is a bit different, I have 3 X 27" in Eyefinity and the dam ryzen master interface is spread across all three screens; it will not allow me to change the display size smaller. any help in this department, please?

Running 3 x 1080p AOC G2770PF's and having the same issue as madhunter..

Launching Ryzen Master gives the warning page but the warning is cropped top and bottom so badly that only the grey and red text is shown OK Cancel buttons are invisible and text is 1 inch tall......

Cannot move or resize this window at all...

Same with the app itself once it is open, everything is enlarged, the window can be reduced but not enough to span only 1 screen..

IMO it seem to force a 4k window size if you launch ryzen master on 3 x 1080p monitors.

Stumbled on a workaround I think (works for me at least no idea if it'll do likewise on 1440p or 4K screens).

Disable eyefinity display group, launch ryzen master and the full warning page is displayed and the app window is now ok and can be resized within a single panel, re-enable eyefinity desktop group and the Ryzen Master window remains the same size it was on a single display and can be resized at need.

Would be better if AMD actually fixed this as i stopped using Ryzen master altogether thanks to it........
